IBM xSeries 360 Boot issues

[Torkum73]

Hi,

I am tinkering in my spare time with legacy server equipment.

Even if it is completly out of date, the resilience of the hardware ist phenomenal.

 

I got my hands recently on an old IBM eServer xSeries 360 8686 2EQ.

 

It posted ok, but had issues with the ServeRAID 4m Controller, whose battery has leaked all over the controllerboard.

 

I removed the battery and startet to update the ASM firmware and such via ASM.

 

Somehow I got a faulty disk image to boot with and since then, the server will not post anymore.

It turns on, the display lights up, displays the IBM logo and the number of installed CPU's and then reboots.

 

I reset the ASM card to factory defaults and even changed the mainboard, since the USB ports were shot, CR2032 recepticle was broken and additional damage from the bad battery from the RAID controller.

 

Remote access to the ASM is still possible, nothing in the log.

 

Any ideas how to get it up and running again?

Does anyone have the codes for the two 7-segment displays on the memory adapter?

Or the description of the two jumpers on the ASM card?

 

I cannot find anything in the IBM documentation.

 

Thanks for reading this

 

Happy New Year
